Project description:Collagenase digestion (d) and cellular outgrowth (og) are the current modalities of meniscus fibrochondrocytes (MFC) isolation for bioengineering and mechanobiology related studies. However, how these modalities may impact study outcomes are unknown. Here, we show og- and d-isolated MFC have distinct proliferative capacity, transcriptomic profiles via RNA sequencing (RNAseq), extracellular matrix (ECM)-forming and migratory capacities. Our data show that microtissue models developed from og-isolated MFC display a contractile phenotype with higher expressions of α-smooth muscle actin (ACTA2) and transgelin (TAGLN) and are mechanically stiffer than their counterparts from d-MFC. Moreover, we introduce a novel method of MFC designated digestion-after-outgrowth (dog). The transcriptomic prolife of dog-MFC are distinct from d-and og-MFC including a higher expression of mechanosensing caveolae-associated caveolin-1 (CAV1). Additionally, dog-MFC were superior chondrogenically and generated larger-size microtissue models containing a higher frequency of smaller collagen fiber diameters. Thus, we demonstrate that the modalities of MFC isolation influences the downstream outcomes of bioengineering and mechanobiology-related studies.

Project description:The aim of this study is to demonstrate that mechanical unloading via SMG will induce a higher osteoarthritic-like gene profile in bioengineered meniscal cartilage from healthy female MFC versus healthy male MFC. This would serve as the molecular basis for early onset of knee osteoarthritis in females

Project description:Genome-wide cDNA array from HT29,HT29-shROR,HT29-Mock, AGS, AGS-shROR, AGS-Mock cells We used microarrays to detail the global programme of gene expression and identified significantly changed genes after ROR depletion. HT29,HT29-shROR, HT29-Mock, AGS, AGS-shROR, AGS-Mock cells were selected for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Aicardi-Goutières syndrome (AGS) is a severe childhood inflammatory disorder that shows clinical and genetic overlap with systemic lupus erythematosus (SLE). AGS is thought to arise from the accumulation of incompletely metabolized endogenous nucleic acid species owing to mutations in nucleic acid degrading enzymes TREX1 (AGS1), RNase H2 (AGS2, 3 and 4) and SAMHD1 (AGS5). However, the identity and source of such immunogenic nucleic acid species remain undefined. Using genome-wide approaches, we show that fibroblasts from AGS patients with AGS1-5 mutations are burdened by excessive loads of RNA:DNA hybrids. Using MethylC-seq, we show that AGS fibroblasts display pronounced and global loss of DNA methylation and demonstrate that AGS-specific RNA:DNA hybrids often occur within DNA hypomethylated regions. Altogether, our data suggest that RNA:DNA hybrids may represent a common immunogenic form of nucleic acids in AGS and provide the first evidence of epigenetic perturbations in AGS, furthering the links between AGS and SLE.
